Problems solved by technology

During the working process, the main working condition of the motor grader is low-speed and heavy-load reciprocating operation. For example, in the common setting of six forward gears and three rear gears (six forward gears and three reverse gears), the most frequently used is the forward two gears. However, according to the control logic of the existing motor grader gear mechanism, the shifting operation needs to be sequentially increased or sequentially decreased. In the actual construction process, the shift to The target gear needs to be operated frequently, and the gear shifting operation is complicated, which will easily cause operator fatigue and affect the efficiency of construction work, and it is easy to wear the gear mechanism and related equipment, shortening the service life

Embodiment 1

[0055] This embodiment provides a gear shift control method for a motor grader with a gear mechanism. The gear mechanism is provided with a neutral gear and a plurality of travel gears, such as figure 1 As shown, the shift control method includes:

[0056] Step S110: receiving a gear shift command from the motor grader;

[0057] Step S200: Control the gear of the gear mechanism to switch from neutral gear to the default starting gear according to the gear shift instruction,

[0058] Wherein, the transmission ratio of each traveling gear is different, and the default initial gear is any one of the multiple traveling gears.

[0059] The shifting control method in this embodiment is used for a motor grader with a gear mechanism. The gear mechanism is provided with a neutral gear and a plurality of traveling gears. The transmission ratio of each traveling gear is different, and the initial gear of the gear mechanism is for neutral. In the gear shift control method, through step S...

Embodiment 2

[0061] This embodiment provides a gear shift control method for a motor grader with a gear mechanism. The gear mechanism is provided with a neutral gear and a plurality of travel gears, such as figure 2 As shown, the shift control method includes:

[0062] Step S110: receiving a gear shift command from the motor grader;

[0063] Step S210: Control the gear of the gear mechanism to switch from neutral gear to the first initial gear according to the gear shift instruction, wherein the first initial gear is a gear among the multiple traveling gears except the gear with the largest transmission ratio.

[0064] In this embodiment, the default starting gear includes the first starting gear, and the first starting gear is a gear other than the gear with the largest transmission ratio among the multiple traveling gears. The lower the gear, the greater the transmission ratio. According to the frequency of use of each driving gear in the daily construction process of the grader, the g...

Embodiment 3

[0067] This embodiment provides a gear shift control method for a motor grader with a gear mechanism. The gear mechanism is provided with a neutral gear and a plurality of travel gears, such as Figure 4 As shown, the shift control method includes:

[0068] Step S101: receiving a manual setting instruction corresponding to the first starting gear;

[0069] Step S102: According to the manual setting instruction, set the gear corresponding to the first starting gear;

[0070] Step S110: receiving a gear shift command from the motor grader;

[0071] Step S210: Control the gear of the gear mechanism to switch from neutral gear to the first initial gear according to the gear shift instruction, wherein the first initial gear is a gear among the multiple traveling gears except the gear with the largest transmission ratio.

[0072] In this embodiment, by adding steps S101 and S102 before receiving the shift command, the gear corresponding to the first starting gear can be set in adv...

Abstract

The invention provides a shift control method, a shift control system and a motor grader. Wherein, the shift control method is used for a grader with a gear mechanism, and the gear mechanism is provided with a neutral gear and a plurality of forward gears. The gear shift control method includes: receiving a gear shift instruction of the grader; controlling the gear mechanism according to the gear shift instruction The gear is switched from neutral to the default starting gear, wherein the transmission ratio of each traveling gear is different, and the default starting gear is any gear in a plurality of traveling gears. Through the technical solution of the present invention, the gear shifting operation can be quickly realized, the number of gears passed through during the gear shifting operation is reduced, the efficiency of the gear shifting operation and the working efficiency of the motor grader are improved, and it is beneficial to relieve the operating fatigue state of the operator , Reduce the wear of the gear mechanism and the transmission gear of the motor grader.

Description

technical field [0001] The invention relates to the technical field of motor grader gear position control, in particular, to a gear shift control method, a gear shift control system and a motor grader. Background technique [0002] At present, the motor grader is one of the common construction machinery, which is mostly used for earthwork leveling operations. During the working process, the main working condition of the motor grader is low-speed and heavy-load reciprocating operation. For example, in the common setting of six forward gears and three rear gears (six forward gears and three reverse gears), the most frequently used is the forward two gears. However, according to the control logic of the existing motor grader gear mechanism, the shifting operation needs to be sequentially increased or sequentially decreased. In the actual construction process, the shift to The target gear needs to be operated frequently, and the gear shifting operation is complicated, which wil...
